SPLIT'IING-MACHIN'E.

Application filed .Tune 21,

Z 0 all whom it may concern Be it known that we, JOHN N. JoHNso and OLAF- C. HANsoN, citizens of the United States, residing at Fertile, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Splitting-Machines, of which the following is a specification.

This invention relates to a wood splitting machine.

The object of the invention is to provide a machine of this character so constructed as to rapidly split blocks of wood and which may be operated by the expenditure of a very little power.

Another object is to provide a simple and economical machine of this character which may be fitted on a medium sized wagon for transportation and use.

WVith these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention. 1

In the accompanying drawings:

Figure 1 represents a side elevation of the machine constituting this invention, and,

Fig. 2 is a top plan view thereof.

In the embodiment illustrated a supporting frame 1 is shown constructed of laterally spaced side bars 2 and 3 connected at their ends by cross bars 4 which are shown seecured to the lower faces of the side bars. A. cross-bar 5 and a platform 6 are secured to the upper faces of the side bars at the opposite ends of the frame, platform 6 being designed to support the blocks of wood to be split.

Two longitudinally disposed parallel laterally spaced beams 7 and 8 are mounted on the frame and carry on their upper faces transversely alined bearings 9 in which is rotatably mounted a shaft 10. Secured to the shaft 10 is a belt pulley 11 with a driving belt 12 arranged thereon and around a pulley 13 mounted on a crank shaft 14 at the front of the machine. This pulley 13 is carried by one end of the crank shaft 14 while fly wheels 16 and 17 are also carried by said shaft the shaft being driven by a suitable engine indicated at 15. i

A belt tightener 18 is shown engaged with the belt 12 and is carried by a bar 19 pivoted at one end to the frame 1 and yieldably con- Specification of Letters Patent.

and is designed for a purpose presently to be described. Two pairs of standards 21 and 22 rise from the beams 7 and 8 those of each series being spaced longitudinally apart and the foremoststandards 22 are preferably made higher than those 21 and have mounted between them a shaft 23.

A lever 24 is fulcrumed between the upper 2 ends of the standards 21 and carries at its front end a pair of hangers 25 which support thecutter 26 an additional brace rod 27 being also employed to connect the cutter 26 with the hangers 25.

A lever 28 is fulcrumed intermediately of its ends. between the Standards 21 as shown at 29 with its front end connected with the hangers 25 as shown at 30. The rear end of this lever 28 is longer than the front end and rests on the perimeter of the cam 20. The cam operates to raise the rear end of lever 28 and lower its front end forcibly actuating the cutter 26 to cause it to split thewood placed thereunder between it and platform 6. A. coil spring 34 connects the rear end of the lever 24: with the lower end of one of the standards and is adapted to raise the cutter after it has been lowered into cutting operation by the cam when the cam moves from under the lever 28 or rather when the cam lowers under the lever.

Suitable brace rods 31, 32 and 33 connect the standards 21 and 22 with the frame 1 to reliably support said standards and enable them to resist all strains to which theymay be subjected.

In the use of this invention the blocks of wood to be split are placed on the platform 6 under the cutter 26 and the engine is started which causes the rotation of the driving wheel or pulley 11 and actuates the cam which rotates very rapidly and causes the cutter to reciprocate sixty strokes per minute, more or less. The operation of this machine requires very little power and it may be actuated by a two horse power engine and two men. only are necessary to feed and control the machine.

- It is of course understood that this machine may be mounted on any suitable support being especially designed to fit on a medium sized wagon so that it may be readdesired.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modificationswithin the scope of the claims may be made in the construction without departing from the principle of the invention or sacrificing anyof its advantages. V

lVhat is claimed is:

1. In a machine of the class described, a supporting frame, a cam mounted thereon, operating means for said cam, a pair of vertically spaced levers supported on said frame, hangers attached to the front ends of said levers, a cutter carried by the lower ends of saidha-ngers, a coiled spring connected with one of said levers for raising the cutter, the other lever being engaged With said cam whereby the cutter is lowered by the rotation of the cam.

2.111 a machine of theclass described, a supporting frame, a driving wheel mounted therein, means for actuating said wheel, a cam disk connected to be operated by said wheel, a pair of vertically spaced levers sup ported on saidframe, hangers attached to the front ends of said levers, a cutter carried by the lower end of said hangers, a coiled spring connected with one of said levers for raising the cutter, the rear end of the other lever resting on the perimeter of said cam whereby the cutter is lowered. 'bythe rotation of the cam.

In testimony whereof we afiix our signatures hereto.
